Finally you did it.
The next step to add a LPS for it.

Yes, have to find Master Lau again.

Already 1/3 cheaper than LevelOne GVS-3110 (need to order and no stock usually)

Now Planet have stock and just take it.

Need to buy Sanwa Cat7 STP LAN cable again.

Just try this Monday by using Planet brand and model GT-802 (bought in SSP) - multi-mode.

I actually have 2 sets of single mode optical-Ethernet media converters running, one between the wifi router and switch, and the other between switch and streamer. Both powered by LPS made by Kenneth.

2 weeks ago I had to take out the one between switch and streamer for a few days for changes to be made in the configuration. The loss in clarity, details and balance were large enough for me to lose interest in switching the system on.

Do the media convertor also need long time to get run-in before have good sound ? like LPS

I think a couple of days

Regarding the converter, I have to take back what I said. Different ppl has different ears, I recommend 2 of my friends to buy the fiber box, neither of them likes it, mainly complaining about loss of details. But my experience is the fiber box enlarges the soundstage, increases the separation and layering by a large margin that I just can't go back to listen without it. Hence, I'll have to remind all fiber box may not be your cup of tea. Trial before buying is recommended.

nickif,

it's usual for them to feel something are lost. but it will take some time to realize what are lost.

yes, analog harmonic feel is reduced especially when use between hub switch to DS player, although sound stage larger.
But how to power (use LPS or not) supplies those pair of convertors is important, I think. Of course, need to use high analytic LAN cable (like Sanwa) also help.

That's why I don't go for a fibre box - need to use LAN cable and LPS to fine tune myself.

that's usual. have you ever thought of the so-called harmonics are not really something that is in harmony with the music?

the less harmonic result is I compare when listen to same music track with & without using media convertor with same Sanwa LAN cable. Of course, I unplug those 2 power adapter (5V2A) first when do the without test.

That's why now I use them to connect between hub switch and wifi router, I can keep the same detail as before, and instrument sound is more clearly outlined.

What puzzled me is the fact that I never feel loss of anything, all the details are there, even more noticeable due to lower noise floor...

代理中環聲望，放LPS在兩塊上面, 餘下一塊給NAS就very good.

I think what u like is the sound of your lps. Try get the same lps to power your fiber boxes and the result should be quite different. Using switching ps for fiber boxes defeats the purpose of having it, i.e. to isolate switching noise from computer. By introducing switching noises back in the last part of the data chain (before your ds player) is the reason for bad sound and loss of harmonics

Agreed. Fibre box or Media converter have to use LPS to give power; otherwise, defeat the purpose of noise reduction (because I change the socket position in my ordinary power bar can hear the different level of purity affection). I forsee the benefit will be more than double after use LPS for media converter together with my d-link wifi router.

Aluminum foil 落線做shielding都係麻麻地，要copper網/管先好點。可能差不多道理。
